“People don’t want us to play the role of deciding for them what’s true and what’s not true but they do want people to play a much stronger role providing context,” Mr Pickles said.

The fine line is similar to one taken by Facebook, which has said it does not want to be an “arbiter of the truth” but has arranged for third-party fact checkers to review falsehoods on its site.

One example of a disputed tweet that might be labelled includes claims about the origin of Covid-19, which remains unknown.

Conspiracy theories about how the virus started and if it is man-made have swirled around social media for months.

Twitter will continue to take down Covid-19 tweets that pose a threat to the safety of a person or group, along with attempts to incite mass violence or widespread civil unrest.

The company has already been removing bogus coronavirus cures and claims that social distancing or face masks do not curb the virus’s spread.

Twitter announced in February a similar initiative to label doctored or manipulated photos or images on its site after a video of Democratic politician Nancy Pelosi was slowed down to make it appear as if she slurred her words.

Since then, Twitter has only applied the label twice to manipulated media.

Tech giants Google, Facebook, YouTube and Twitter have responded to a global spread of misinformation that has moved with the virus since the outbreak began in January.

Last month, Facebook also began alerting users who interacted with coronavirus misinformation by directing them to the World Health Organisation’s fact page.
